@AllisonRoyal
Do you understand about 'common denominators'?

Answer 5

yes

Answer 6

So to add these numbers you need to put them over a common denominator

the quickest value to us is 40

what is 7/10 when the denominator is 40?

what is 1/4 when the denominator is 40?

Answer 7

40/10 and 40/4

Answer 8

no - it is the BOTTOM of the fraction that becomes 40

so for instance 8/20 is the same as 16/40 (simply multiply top and bottom by 2)

so what is 7/10 the same as (?/40)

what is 1/4 the same as (??/40)

Answer 9

7/40 1/40

Answer 10

no

you need to multiply top and bottom by the same

so
3/10 becomes 12 /40 because you multiply 10 by 4 you must multiply 3 by 4 as well

so if 3/10 becomes 12/40 what does 7/10 become = ?/40
